The Hirschmann M-SFP-LX/LC (Part No. 943 015-001) is an industrial-grade, SFP (Small Form-Factor Pluggable) optical transceiver module designed for reliable data transmission in harsh environments.
Key Product Overview:
-
Form Factor: SFP (Mini-GBIC)
-
Interface: Duplex LC fiber optic connector
-
Transceiver Type: 1000BASE-LX (Long Haul) for single-mode fiber.
-
Primary Application: Converts the electrical signals from a switch/router’s SFP port into optical signals for transmission over fiber optic cabling, and vice-versa.
Technical Specifications:
1. Performance & Standards:
-
Compliance: IEEE 802.3z 1000BASE-LX
-
Data Rate: 1.25 Gigabits per second (1 Gbps)
-
Wavelength: 1310 nm (nominal)
-
Fiber Type: Single-Mode Fiber (SMF)
-
Maximum Reach: Typically up to 10 kilometers (6.2 miles), depending on fiber quality and link budget.
2. Optical & Electrical Characteristics:
-
DDM/DOM Support: Digital Diagnostics Monitoring (DDM) is typically supported, allowing real-time monitoring of parameters like:
-
Transceiver temperature
-
Laser bias current
-
Transmitted optical power
-
Received optical power
-
This enables predictive maintenance and fault isolation.
-
-
Dual Power Supply: Designed to work with the dual, redundant power supplies common in Hirschmann industrial switches.
-
Low Power Consumption: Industrial-optimized for efficiency.
3. Physical & Environmental Design (Industrial Focus):
-
Extended Temperature Range: Operates reliably in a wide temperature range (e.g., -40°C to +85°C / -40°F to +185°F), suitable for industrial control rooms, railway trackside, or outdoor cabinets.
-
High MTBF: Manufactured for high Mean Time Between Failures, ensuring long-term reliability in 24/7 operations.
-
Robust Housing: Built to withstand higher levels of vibration, shock, and EMI/RFI interference compared to commercial-grade SFPs.
-
SEO Variant: “SEO” in the description often indicates it is a Selected Engineering Offer or a specific version validated and supplied by Hirschmann for guaranteed compatibility and performance in their devices.
4. Compatibility:
-
Vendor Interoperability: While designed for and tested with Hirschmann (now part of Belden) switches and networking equipment (e.g., MS, MACH, RSP families), it is standard-based and should work in any SFP port that supports the 1000BASE-LX standard.
-
Device Compatibility: Plugs into any standard SFP/SFP+ slot. Crucially, it is MSA (Multi-Source Agreement) compliant.
Typical Applications:
This transceiver is ideal for creating robust, long-distance backbone connections in:
-
Industrial Automation & Process Control (Factory floors, SCADA networks)
-
Transportation Systems (Railways, Traffic Management)
-
Power Utility & Substation Networks
-
Oil & Gas (Pipelines, Refineries)
-
Marine & Offshore installations
-
Any application requiring noise immunity, long distance (>550m), and operation in extreme temperatures.
